lwIP was recently updated in a89ac9e24a566e45bd3ffa7ef9e61e1d994616ea to STABLE-2_2_0_RELEASE, and this introduced a change in the configuration variable `DHCP_DOES_ARP_CHECK`, renaming it to `LWIP_DHCP_DOES_ACD_CHECK`. This commit fixes the ports lwIP settings to use the new configuration option. Without this option, connecting to a WiFi access-point takes about 12.5 seconds. With this option (ie disabling DHCP ARP checks) connecting takes about 4 seconds. Tested on an RPI_PICO_W and PYBD_SF2. Signed-off-by: Damien George <damien@micropython.org>
